Subject: [PATCH 22/22] platform/x86/intel/pmc: Add NVL PCI IDs for SSRAM telemetry discovery
Date: Thu, 12 Mar 2026 18:52:01 -0700 [thread overview]
Message-ID: <20260313015202.3660072-23-david.e.box@linux.intel.com> (raw)
In-Reply-To: <20260313015202.3660072-1-david.e.box@linux.intel.com>
Add Nova Lake S PMC device IDs to enable binding of the SSRAM telemetry
driver on NVL platforms, and map them to the ACPI-based discovery policy.
Signed-off-by: David E. Box <david.e.box@linux.intel.com>
